Abstract

A front steering module adapted for integration with the subframe of a zero-turn radius vehicle incorporating an electronic steering apparatus. The module provides both front wheel steering and corresponding control inputs for the electronic steering apparatus. The module has a frame member having a pair of steered wheel assemblies mounted thereto and a mounting member for attachment to the vehicle. The module further comprises a steering mechanism and a steering position sensor for providing input to the electronic steering apparatus.
